Physics Question, Please Help Me?

Which line in the graph might you obtain if an increase in x always produces a linear increase in y? A, B, or C?

Answer 1

Here's something I'll bet you never thought about before:

A function is called "linear" if it makes a straight line when you graph it.

There are three different functions on the graph you provided. The only one of them that's a "linear" function is line B .
